The country has endured a record-breaking cold snap for much of the winter period but there are no signs of any respite, with some parts of the US set to remain in subzero temperatures for weeks to come.
A combination of low pressure and high winds will track close enough to the US east coast to bring everything from snow and ice to blizzard conditions and frigid winds later this week.
This low is forecast to track onto Nova Scotia at peak intensity, somewhere in the range of 950mb, having gone through a pressure drop of more than 30mb in 24 hours. This means strong winds, heavy snowfall and blizzard conditions are expected.
The storm qualifies as a 'weather bomb' – a meteorological term for a storm that features a drop in pressure of around 24 millibars over a 24 hour period.
The storm will undergo rapid strengthening, know as bombogenesis, as it moves up the east coast and Maine and New Brunswick are expected to face the brunt of the storm with up to 24 inches of snow forecast.Related articles

When bombogenesis happens, the low-pressure systems can create hurricane-force winds. Even though they are not technically hurricanes, many will call this a "winter hurricane."
Blizzard conditions are expected for some exposed areas on the east coast, including New York’s Long Island and parts of Connecticut and Maine.
Some people have been warned to expect power outages and to avoid travelling unless absolutely necessary, with flight delays and cancellations likely.
South Carolina Department of Transportation (SCDOT) tweeted: “SCDOT encourages residents and visitors in South Carolina’s coastal counties to stay off the roads if possible as winter weather moves into the state on Wednesday.
